käytettävyysheuristiikkajoukosta

Käytettävyysheuristiikkajoukko refers to a set of usability heuristics, which are general principles or rules of thumb for designing user interfaces. These heuristics are not definitive guidelines but rather a collection of best practices that can help designers identify potential usability problems in an interface. The most well-known set of usability heuristics was developed by Jakob Nielsen and Rolf Molich in 1990.

The primary purpose of usability heuristics is to provide a framework for evaluating and improving the usability of a system or application. By applying these heuristics, designers and evaluators can systematically examine an interface and pinpoint areas where users might encounter difficulties or confusion. This proactive approach to usability testing helps in identifying and fixing issues early in the design process, which is generally more cost-effective than making changes later.

Nielsen's 10 Usability Heuristics include principles such as visibility of system status, match between system and the real world, user control and freedom, consistency and standards, error prevention, recognition rather than recall, flexibility and efficiency of use, aesthetic and minimalist design, help users recognize, diagnose, and recover from errors, and help and documentation. Each heuristic addresses a different aspect of user interaction and experience. For example, "visibility of system status" means that the system should always keep users informed about what is going on through appropriate feedback within a reasonable time.

Usability heuristics are widely used in user interface design, software development, and web design. They serve as a valuable tool for designers, usability experts, and even end-users to assess and discuss the quality of a user interface. While they are not a substitute for actual user testing, they offer a quick and efficient way to perform a heuristic evaluation, providing insights into potential usability issues before extensive testing is conducted.
